Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an armrest for a door/flank of a motor vehicle, which comprises a shoelace member made of plastic foam and having a mat-like relatively flexible insert layer and a fastening part side. Regarding force/ζ-. Furthermore, the invention relates to a method for manufacturing such an armrest cover and an apparatus for implementing this method.

Car doors will be equipped with increasingly larger door knobs inside the car. The door nomennel consists of a relatively bending-resistant plate, preformed in one piece from cardboard or the like, and has an inner bend, an outer bend and, in particular, an armrest as an integrated component.

Armrests integrated into the door flannel are designed to replace the conventional armrests. However, since the materials used for the door panel sills are relatively hard, a considerable part of the comfort of the vehicle's equipment is reduced by this measure.

Therefore, highly equipped automobiles are equipped with a cover that provides cushioning within the area where the armrest of the door panel is incorporated. German Patent Application No. 3,107,760 already describes a cushioning force ζ-, in which case the insert layer supporting the cushioning element advantageously consists of a thin mat. That's all there is to it. The invention starts from a cover of the above-mentioned type which is provided with a mechanical property.

By the way, the object of the present invention is to combine a cover of the type mentioned at the beginning with another active part so that even if the total height of the cover is small, the cover can provide a good notation effect and can be extended without problems. It is important to consider the following. A further object of the present invention is to provide a method for manufacturing such a cover and an apparatus for carrying out this manufacturing method.The means provided by the present invention to solve this problem are as follows. That is, the above-mentioned insertion layer is positioned on the back side of the KNONOYON member, and the above-mentioned 22787 member is connected to the insertion layer. It has a fixing element fixed between it and the cushioning element, and in the end region of the cushioning element it has an integrally molded grip part with a reinforcing insert layer made of a shape-stable material arranged inside. Moreover, the reinforcing insertion layer is fixed to the door/ξ panel at both ends by fixing members.

Since the arrangement of the insert layer is uniquely limited and is placed on the back surface of the cushion member, the entire plastic foam formed on the insert layer is closely bonded with the insert layer, and It serves the purpose of a 7-piece shoe, thereby ensuring a sufficient cushioning effect even with a small wall thickness. Placing the fixing member directly in contact with the insertion layer located between the door panel and the fixing member at a relatively stable part of the force/S-, that is, the installation position of the force/S-, is problematic. No guarantee of reliable fixation. A means for integrally molding a grip part on a cushion member, firmly reinforcing the grip part with a reinforcing insertion layer, and configuring the reinforcing insertion layer so that the reinforcing insertion layer can be fixed to the door/ξ panel at both ends is provided. Special effects are provided as follows. This means that the manufacture and separate mounting of a grip, which is necessary in particular for closing the door, although it is for opening the door of the motor vehicle, can be omitted.

It is indeed known to construct an armrest in a motor vehicle in one piece with a grip, but in this case the armrest is a relatively large-volume component which extends above the grip area and has a shape-stable insert layer. It is. Such a shape-stable insert layer is manufactured from sheet metal or plastic injection molded parts that are integrally or rigidly connected to each other or from sheet metal and plastic injection molded parts that are combined and rigidly connected to each other. On the one hand, the materials and costs are very high and dusty, and on the other hand, they are therefore not suitable for a cover of the type according to the invention. This is because in the cover according to the invention an increased dimensional stability should be provided primarily for the grip part.

The reinforcing insert arranged in the grip part preferably consists of a sheet-metal molded part that is approximately U-shaped.

The sheet-metal molded part has a low weight, can be manufactured easily and cost-effectively, and can provide the grip part with a strength that is more than sufficient to meet the technical requirements.

In an arrangement according to the invention, the fixing elements fixed in the shoe/yong element may each consist of a base plate adjoining the insert layer, said base plate optionally having a hole for screwing in a set screw. It has a pin-shaped fixing ring which penetrates the insert layer or is adapted to be fixed in a corresponding receptacle of the door ξ flannel. In the first possibility, the door panel is attached to the door of the motor vehicle on the right front, and the cover is pre-attached to the door nose panel. The second possibility makes it possible to later install the cover on a door that is already equipped with a door panel.

The fastening element can be designed as a metal part or as a plastic injection molded part. These components are clearly mass-produced products that do not cause significant costs, are quick and easy to install, and are made in one piece after the foaming process. There is no need for cleaning, which is disadvantageously the case with molded insert tongues and the like.

In another embodiment of the invention, the cushion member has a relatively flat longitudinally elongated structure and has a substantially rectangular basic shape with chamfered edges both in plan view and in cross-section. have. The cushion member is configured in a longitudinally elongated manner and is configured in an L-shape in its cross-sectional view, and includes a support leg and a support leg positioned substantially at right angles to the support leg and provided with a fixing member. may alternatively be provided. Whereas in the first case the pure cushioning effect of the armrest basin of the door flannel is provided in connection with the grip part, in the second case an additionally rigid partial side of the door flannel is provided. There is a side cushion effect and a separation seam covering effect.

A further embodiment of the invention results from the fact that the insert layer of the cushioning element, which advantageously consists of a glass staple fiber cloth, partially overlaps the reinforcing insert layer of the grip part. As a result, a zone of high stability is created in the transition area between the cushioning element and the gripping element.

In accordance with the present invention, the method provided for producing a cover using a foam mold which can be closed by a lid includes applying the insert layer of the reservoir of the shoe 737 member to the lid and attaching the insert layer to the lid by means of a fixing member. The reinforcing insertion layer of the fixing/grip part is positioned within the foamed i2 layer, the difference is closed, and the sword is inserted.
This is noticeable by foam-molding the mold cavity of the foam-molding mold after this process.

A particular advantage of the manufacturing process according to the invention is that the insert layer of the cushion element reservoir is fixed in a predetermined position and also remains in this position during the foaming process.

The device provided according to the invention for carrying out this process essentially consists of a foam mold, the mold cavity of which can be closed by a lid, the lid having a receptacle for holding a fixing member. It has certain characteristics. In this case, the attachment part may optionally be designed as a pin projecting perpendicularly from the lid wall or as a blind hole machined in the lid wall. With this device structure according to the invention, the fixing element can not only be positioned and placed quickly and easily, but at the same time it serves significantly for the positioned fixation of the insert layer.

The invention will now be described in detail with reference to the drawings.

The cover illustrated in FIG. 1 consists of a cushion member 1 and a grip portion 2 integrally molded onto the shoe 7/member 1. The cushioning element 1 and the gripping part 2 are primarily formed from plastic foam and have a skin, which can consist of a foam material or preferably of a previously rotomolded and then foamed skin. You can leave it there.

The cushioning member 1 has an insert layer 3 consisting of a section of relatively flexible, preferably glass stable fibre, cloth.
The insert layer 3 is located on the back side of the cushioning element 1 and, even if only limited by the cross structure, produces a close bond with the plastic foam. The grip part 2 is provided with a reinforcing insert layer 4 made of a shape-stable material. The reinforcing insert layer Φ shown drawn out for better visibility is particularly advantageously made of a piece of sheet metal strip, which piece is bent approximately into a U-shape as shown. The end portion 5 may be constructed as a curved shape and has a bent end portion 5.

In contrast to the insert layer 3, the reinforcing insert layer 4 has a bent end 5.
Except for the grip part 20, which is completely embedded within the plastic foam, thus increasing the strength of the grip part 20. Thereby, the grip part 2 can be used both for clinging to the door of a motor vehicle and for opening and closing the door, without overloading the grip part 2.

In this connection, it is important that the grip part 2 is fixed in both its end regions in part to the door ξ panel η, which is illustrated in FIG. The bent ends 5 of the reinforcing insert are provided for the purpose of securing the grip part 2 on both sides. In this case, both ends can be fixed, for example, by screws that can be screwed into the holes 7 from the back side of the door nominal 6. It is still possible to equip the bent upper end 5 of the reinforcing insert layer 4 with a pin 8, which has an outwardly projecting projection 9. Thereby, the cover can be connected in a snap-on manner with the upper free end of the grip part into the corresponding receptacle of the door panel and the remaining area can be connected to the door panel 6 by means of screws or other fastening elements, such as clips.
can be fixed to.

The cushion member l includes a plurality of fixing members 10. In the embodiment shown in FIG. 1, the fastening elements l○ each consist of a pace plate 11 with a fastening arm 12 bent twice backwards and a pin-like fastening clip 13 pointing forward. . This fixing member 10 is
11 are arranged on the cushioning member 1 in such a way that each insert layer δ and the plastic material placed on the inserting layer 3 are located and the fixing clips 13 protrude from the back side of the cushioning member l. has been done.

By connecting the pin 8 in the corresponding receptacle of the door ξ panel 6 in a snap-fit manner and the fastening element 10 in a snap-fit manner, it is possible, in particular, to attach the door ξ already installed.
It can be quickly and easily attached to the panel 6 even later. In this case, a snap-fit connection can also be made in the area of the bent lower end 5 of the reinforcing insert layer 4 by means of a clip 14, which is only shown in dash-dotted lines, and which also extends vertically downward. It may also be placed facing towards.

While the cushion member 1 shown in FIG. 1 has a substantially rectangular configuration in both a plan view and an end view, the cushion member 1 shown in FIG. 2 has an L-shape in cross section. It has a support leg 15 and a support leg 16 positioned substantially perpendicular to the support leg 15.

However, from a fundamental point of view, the cover shown in FIG. 2 is of similar construction to the cover shown in FIG. The cover has in the cushioning element 1 a cloak-like flexible insert layer 3, in this case configured in a cross-section, and a reinforcing insert layer 4 consisting of a piece of sheet metal in the grip part 2. The reinforcing insert layer 4 extends into the support leg 16. The bent lower end 5 of the reinforcing insertion layer 4 is connected to the support leg 1
6 protrudes from the back side, for which purpose the insert layer 3 is provided with a cutout 17.

The underside of the support leg 16 has a material area 18 that is slightly drawn forward, which provides additional wall space for the fastening element 10 positioned here and by which the door panel 6 is obtained. The fastening member shown in FIG. 2 has a pace plate 11 and a double-folded fastening arm 12, similar to the fastening member shown in FIG.

However, in this case instead of the fixing clip 13, a hole 18' is provided for the set screw.

In FIG. 3, the armrest area of the door ξ-flank 6 is shown together with a cover of the type according to the invention fitted over this area. In the example shown here, screw fastening has been selected both for the grip part 2 and for the molded part 1, which is made clear by the set screw 19 shown.

In FIGS. 4 and 5, a partial area of a lid 20 of a conventional foam mold, which is not shown, is shown. This lid 20 has a mounting portion for holding the fixing member 10. The mounting part shown in FIG. 4 consists of a pin 21 and a fifth
The mounting shown in the figure consists of a blind hole 22.

When manufacturing the cover, the insertion layer 3 is first applied to the lid 2o and fixed to the lid 20 by the fixing member 10. The fastening element 10 itself is held in place only by a frictional connection and can therefore be easily removed again. The reinforcing insert layer 4, which has generally been passed through the rotomolded part, is positioned and fixed in a foam mold (not shown), after which the lid 20 is closed and the mold cavity is foam molded in a conventional manner. .
